` i INDIANA TAPE WINDING- MACHINE Application led November 15, 1928. Serial No..v319,709.

The invention relates to machines for winding tape on various objectsl such as electrical coils.-

lnthemanufacture of many types of coils vL: the wire is wound on a mandrel or former and removed therefrom whenthe winding is finished7 thereby forming marginal c oils or coils with openings in them. Tape is generally wrapped or wound about they several 10 turns of wire either fully around the coil or at selected points thereon. Since the coil is Y closed it is necessary to pass the tape through the opening in the coil for each turn of the tape about the wires. Heretofore most winds i ing of tape upon closed coils has been done by hand.

The object of our invention is to provide a simple machine which is capable of eiliciently and rapidly winding a tape about the turns 2O of the wire of a coil.- Y

The invention is illustrated in the accompanying drawings in which Q Figure 1 is a central vertical cross-section of the machine; Fig. 2 an end View of the i same; Fig. 3 a plan View of the saine; Fig.

" 30 view of the latter link.

In the illustrative embodiment of the invention 1 represents the frame of the machine, the lower portion being open on one side and adapted to be closed by the removable plate 2. Shafts 8, 4, and 5 are mounted at one end in the fixed side 6 of the frame the opposite ends of the shafts having suitable niountings in the plate 2. A pinion 7 is keyed to the shaft 3, which shaft is driven by suitable power means. The pinion 7 meshes with two double gears 8 and 9 that are mounted upon the shafts 4 and 5 respectively. The teeth of the gears project through slots 10 and L 11 formed in the concaved partition 12 formed on the fraine above the shafts 4 and 5. Guards 13 and 14 project inwardly from the side 6 and the plate 2. The guards are spaced from the partition 12 and curve longituoinally similarly to the partition. The

and rollers 32 are mounted in the opening.

Vwardly eXteriorly ofthe coil it frame, apawl being adapted to, engage the partit-ion and guards form a track for the tape carrier 15. The upper portion of the frame consists of a standard'l suitably secured to the baseand carrying at its upper end a head 17 having a track 18 on its lower side lcorresponding to the track formed by the partition 12 and guards 13 and 14 and adapted to lsupport the tape carrier 15. I The tape carrier is composed ofv a series i of links 19 each of which consists of a curved plate 2O bifurcated at one end and having two parallelupstanding walls 21 atits opposite sides. Teeth 21EL are formed along'the upper edge of eachwall and are adapted to be engaged by the teeth of the gears 8 and'9. A tongue 22 at the opposite end of each plate vis adaptedto be received by the bifurcated end of another suchplateand pivoted thereto by` a pin '23 thereby making possible the forming of ailink belt or carrier. The tongue on one of the links24 is hook shapedso that the hook25 will removably engage the pin in the bifurcated end. of the adjacent link in order that the beltmay be 'separated or opened at said link for insertion of the beltthrough the coil 26 that is to be taped. Each ofthe links carries rollers 27 inserted in openings formed in the plate 20.

The link 28, Figs. 7 and 8, differs from the other links in that a central opening` L29 is formed in the plate 2O2L and rollers 30 are mounted in theopeningin spaced relation.v

An opening 31 is formed in the, standard 16 v15"5 The tape T is led from the spool 33 through the opening 31 and through the opening-'29 in the link 28, the free end of the'tape being secured to the coil.- Y YThe belt is y driven counterclockwse (Fig. 1.) and as the link 28 passes downwardly through the coil and upcarries the tape with it and wraps or winds thetape upon the coil. The coil is held by the operator upony an apertured shelf 34 and he rotates it on the shelf to cause the tape tobe wound spirali uponfthe coil. j f

The shelf 34y is mounted on a rack-35 that is longitudinally movably supported on the rack at any adjusted height and hold it and the shelf in such position.

A band 37 is secured at one end to the partition 12 and is disposed between the side walls of the links. rlhis band projects through a slot 38 formed in the wall of the trame l and its projecting end is suitablj7 attached to a treadle 89. The anchored end et the band and the slot 38 are both adjacent the opposite ends of the track in the lower portion of the trame l hence when the treadlc is depressed the band is drawn against the bottom plates of the links and retards or checks the movement of the belt. The band is therefore a brake to retard or stop the belt when necesv sary.

A shaft l() is suitably mounted brackets il that project from the and upon this shaft are pivotedtivo cylinders 42. ln each cylinder there is a spring 43 engaging at its lower end the head of a bolt ad, and at its other end the spring engages the upper end ci the cylinder. bolt extends through the upper endocylinder and passes through a lever fijo, the nut 4S securing` the bolt to the lever. The levers 45 are pinned to a rock shaft l? that is revolubly mounted on the standard 16. fr. lever 4S is secured to the shaft et? between the levers l5 and projects through a slot di) in the standard into a recess 50 'formed in the head 17, which latter lever under the influence of the springs supports the head and holds it against the adjusting screw 5l, which screw is adjusted in accordance with the desired tightness of the belt.

Another lever 52 is secured to the rock shaft l? and a rod or cable 53 isv attached to the Jfree end of the lever 52 and depends for convenient access by theoperator. By pulling down on the rod or cable 53 the shaft l? opposed by the springs e3, is rocked to cause the lever e8 to lower the head l? and thereby loosen the belt so that the link 2e may be detached from its neighbor'. Upon releasing the rod or cable the'springs 43 cause the head 17 to return to its uppermost position. A guard 54V is verticallyslidably mounted in the head 17 which, whenlowered, protects vthe Operator from contacting with the moving belt and also tends to retain the outer told of the tape in the channel of the belt as it is drawn through the coil .26 and thereby prevent looping of the tape.

What we claim is n l. In a tape winding machine, a frame, a track formed on the trame, an endless carrier slidable on the track, a head slidably mounted on the frame and having a track slidably supporting the carrier, resilient means opposing the movement ofthe head to maintain tension on the carrier, means to move the head to release the said tension, means to drive the carrier, means to support the object to be taped in the path of the carrier and a spool of tape, the free end ofthe tape being extended through the carrier for attachment to the object.

2. In a tape Winding machine, a trame, an arcuate track formed on the frame, a head slidably mounted on the frame and having an arcuate track thereon, an endless link belt slidably mounted on both tracks, means to drive the belt, means to support an object to be tapedin the path of the carrier, a spool ot tape the free end of the tape being extended through one or the links ot the belt for attachment to the object, a rock shaft mounted on the frame, a lever secured to the shaft and engaging the head, a second lever secured to the shaft and a spring opposed member connected to the latter lever and adapted to cause the head to move in one direction for placing tension on the belt and'means to cause the head to move in the opposite direction.

ln witness whereof we have hereunto subscribed our names. j
